DETAILED DESCRIPTION

Reference will now be made in detail to specific example embodiments forcarrying out the inventive subject matter of the present disclosure. Inthe following description, specific details are set forth in order toprovide a thorough understanding of the subject matter. It shall beappreciated that embodiments may be practiced without some or all ofthese specific details.

Disclosed is an augmented reality system to generate and cause displayof an augmented reality interface at a client device. Variousembodiments may detect speech, identify a source of the speech,transcribe the speech to a text string, generate a speech bubble basedon properties of the speech and that includes a presentation of the textstring, and cause display of the speech bubble at a location in theaugmented reality interface based on the source of the speech.

Some embodiment augmented reality systems may include a video and imagecapture system to perform operations that include recording andacquiring images of a space, a graphical interface configured to displaya presentation of the space, and a microphone to receive sound. In someexample embodiments, the augmented reality system receives sounds anddetects speech. For example, the augmented reality system maydifferentiate general ambient noises and sounds from speech based ontechniques known to those skilled in the art, such as Voice ActivityDetection (VAD).

In some example embodiments, the augmented reality system identifies asource of the speech in response to detecting the speech. For example,the source of the speech may include a person (e.g., a person in thespace depicted in the presentation of the space), as well as a radio,television, telephone and/or mobile device, or other similar device thatincludes speakers and which may be configured to output a sound signal.For example, to identify a source of the speech, the augmented realitysystem may apply speech detection or facial landmark recognitiontechniques and other similar techniques to detect a person's lipsmoving. Based on the person's lips moving, the augmented reality systemmay determine that the person (specifically the person's mouth) is thesource of the speech.

In instances where the source of the speech is a radio, television,telephone and/or mobile device, the augmented reality system may applyacoustic source localization techniques. Acoustic source localizationinclude techniques for locating a source of a source given measurementsof a sound field. The sound field can be described using physicalquantities like sound pressure and particle velocity. By measuring theseproperties it is (indirectly) possible to obtain a source direction.

For example, the presentation of the space may include depictions ofmultiple people, each with corresponding user profiles. Having receivedthe speech data (e.g., the speech recorded through the microphone), theaugmented reality system identifies a user profile based on the speechdata through speech recognition techniques. Upon determining the userprofile based on the speech data, the augmented reality systemdetermines which individual depicted in the presentation is the sourceof the speech based on facial landmark recognition data.

In some example embodiments, the augmented reality system transcribesthe speech into a text string based on natural language speechrecognition techniques. In further embodiments, the augmented realitysystem may translate the transcribed text string into one or morelanguages based on user preferences.

Having identified a source of the speech, the augmented reality systemgenerates and causes display of a speech bubble. The size and positionof the speech bubble may be based on the speech data, the text string,and the location of the source of the speech. For example, thetranscribed speech data may have a length based on a total number ofcharacters in the text string. The size of the speech bubble may therebybe based on the total number of characters in the text string. Theposition of the speech bubble in the GUI may be based on the location ofthe source of the speech. The augmented reality system may place thespeech bubble adjacent to the source of the speech. In some exampleembodiments, the augmented reality system may identify significantand/or essential elements in the presentation (e.g., a person orpersons), and place the speech bubble at a position so as not toobstruct the essential and significant elements.

In some embodiments, the augmented reality system may determine anemotional effect of the detected speech based on techniques thatinclude, but are not limited to: analysis of attributes of the speechitself (e.g., volume and cadence of the speech); and a translation ofthe text string of the transcribed speech; as well as facial landmarkrecognition techniques (e.g., based on facial landmarks of a user). Theemotional effect may include anger, sadness, happiness, love, and thelike. In some embodiments, the presentation of the speech bubble and thetext string generated by the augmented reality system may be based onthe emotional effect.

For example, in some example embodiments, the augmented reality systemmay parse the text string of the transcribed speech into individualwords, determine a definition of the set of words, and compare thedefinitions of the words to an emotional effect library. Based on thecomparison, the augmented reality system may determine an intendedemotional effect of the speech. For example, the text string may includea set of words that are typically associated with happiness, eitherliterally, or based on context.

In further embodiments, the augmented reality system may determine theemotional effect of the detected speech based on the speech data, andattributes of the speech itself. For example, the speech data mayindicate a volume, as well as a cadence of the speech. The augmentedreality system may therefore determine the emotional effect based on thespeech attributes, such as the volume and cadence.

In further embodiments, the augmented reality system may determine theemotional effect of the detected speech based on facial landmarkrecognition techniques. For example, having identifies a user as thesource of the speech, the augmented reality system may capture faciallandmarks of the user and apply facial landmark recognition techniquesto determine an emotional state of the user (e.g., based on a smile, afrown, a furrowed brow, etc.). Thus, based on the emotional state, theaugmented reality system determines the emotional effect of the speech.

In some example embodiments, the augmented reality system may detectnon-verbal sounds and identify an appropriate onomatopoeia based on thenon-verbal sounds. Onomatopoeia refers to words that phoneticallyimitate or suggest a non-verbal sound. Words like “bang,” “woof,” and“pop” are examples of onomatopoeia that refer to non-verbal sounds. Upondetecting a non-verbal sound, the augmented reality system may access anonomatopoeia library to select an appropriate onomatopoeia, andgenerates and causes display of a graphical element at a location in theGUI based on the source of the onomatopoeia.

Consider an illustrative example from a user perspective. A clientdevice, executing an application of the augmented reality system, maydisplay a presentation of a space (e.g., a basketball court, an office,a restroom, etc.), wherein the space includes one or more individuals(wherein each individual has a corresponding user profile). Theaugmented reality system may detect speech (e.g., through a microphoneof the client device), and identify a source of the speech in thepresentation of the space based on the techniques discussed above. Forexample, the augmented reality system may detect that facial landmarksof a first individual among the one or more individuals depicted in thepresentation indicate that the first individual's mouth and lips weremoving. Based on the facial landmarks, the augmented reality system maydetermine that the first individual is a source of the speech.

Having determined the source of the speech, the augmented reality systemmay transcribe the speech to a text string. In some example embodiments,the augmented reality system may also translate the speech to adifferent language based on preferences. For example, a user associatedwith the client device itself may specify language preferencesindicating a first language, while the detected speech was in a secondlanguage. Based on the language preferences of the user associated withthe client device, the augmented reality system may translate thedetected speech from the second language to the first language.

The augmented reality system determines an emotional effect of thespeech based on the techniques discussed above. For example, theaugmented reality system may determine that based on the faciallandmarks of the first individual, and definitions of the text string,the emotional effect of the speech is anger. The augmented realitysystem generates and causes display of a speech bubble based on alocation of the first individual (the source of the speech) and thedetermined emotional effect. For example, the speech bubble andcorresponding text may be stylized to indicate the emotional effect.

FIG. 1 is a block diagram showing an example messaging system 100 forexchanging data (e.g., messages and associated content) over a network.The messaging system 100 includes multiple client devices 102, each ofwhich hosts a number of applications including a messaging clientapplication 104. Each messaging client application 104 iscommunicatively coupled to other instances of the messaging clientapplication 104 and a messaging server system 108 via a network 106(e.g., the Internet).

Accordingly, each messaging client application 104 is able tocommunicate and exchange data with another messaging client application104 and with the messaging server system 108 via the network 106. Thedata exchanged between messaging client applications 104, and between amessaging client application 104 and the messaging server system 108,includes functions (e.g., commands to invoke functions) as well aspayload data (e.g., text, audio, video or other multimedia data).

The messaging server system 108 provides server-side functionality viathe network 106 to a particular messaging client application 104. Whilecertain functions of the messaging system 100 are described herein asbeing performed by either a messaging client application 104 or by themessaging server system 108, it will be appreciated that the location ofcertain functionality either within the messaging client application 104or the messaging server system 108 is a design choice. For example, itmay be technically preferable to initially deploy certain technology andfunctionality within the messaging server system 108, but to latermigrate this technology and functionality to the messaging clientapplication 104 where a client device 102 has a sufficient processingcapacity.

The messaging server system 108 supports various services and operationsthat are provided to the messaging client application 104. Suchoperations include transmitting data to, receiving data from, andprocessing data generated by the messaging client application 104. Insome embodiments, this data includes, message content, client deviceinformation, geolocation information, media annotation and overlays,message content persistence conditions, social network information, andlive event information, as examples. In other embodiments, other data isused. Data exchanges within the messaging system 100 are invoked andcontrolled through functions available via user interfaces (UIs) of themessaging client application 104.

Turning now specifically to the messaging server system 108, anApplication Program Interface (API) server 110 is coupled to, andprovides a programmatic interface to, an application server 112. Theapplication server 112 is communicatively coupled to a databaseserver(s) 118, which facilitates access to a database(s) 120 in which isstored data associated with messages processed by the application server112.

Dealing specifically with the Application Program Interface (API) server110, this server receives and transmits message data (e.g., commands andmessage payloads) between the client device 102 and the applicationserver 112. Specifically, the Application Program Interface (API) server110 provides a set of interfaces (e.g., routines and protocols) that canbe called or queried by the messaging client application 104 in order toinvoke functionality of the application server 112. The ApplicationProgram Interface (API) server 110 exposes various functions supportedby the application server 112, including account registration, loginfunctionality, the sending of messages, via the application server 112,from a particular messaging client application 104 to another messagingclient application 104, the sending of media files (e.g., images orvideo) from a messaging client application 104 to the messaging serverapplication 114, and for possible access by another messaging clientapplication 104, the setting of a collection of media data (e.g.,story), the retrieval of a list of friends of a user of a client device102, the retrieval of such collections, the retrieval of messages andcontent, the adding and deletion of friends to a social graph, thelocation of friends within a social graph, opening and application event(e.g., relating to the messaging client application 104).

The application server 112 hosts a number of applications andsubsystems, including a messaging server application 114, an imageprocessing system 116, a social network system 122, and an augmentedreality system 124. The augmented reality system 124 may be or includeany instrumentality or aggregate of instrumentalities operable tocompute, process, store, display, generate, communicate, or applyvarious forms of data for user profile building, audience derivation,control, or other purposes.

The messaging server application 114 implements a number of messageprocessing technologies and functions, particularly related to theaggregation and other processing of content (e.g., textual andmultimedia content) included in messages received from multipleinstances of the messaging client application 104. As will be describedin further detail, the text and media content from multiple sources maybe aggregated into collections of content (e.g., called stories orgalleries). These collections are then made available, by the messagingserver application 114, to the messaging client application 104. Otherprocessor and memory intensive processing of data may also be performedserver-side by the messaging server application 114, in view of thehardware requirements for such processing.

The application server 112 also includes an image processing system 116that is dedicated to performing various image processing operations,typically with respect to images or video received within the payload ofa message at the messaging server application 114.

The social network system 122 supports various social networkingfunctions services, and makes these functions and services available tothe messaging server application 114. To this end, the social networksystem 122 maintains and accesses an entity graph 304 within thedatabase(s) 120. Examples of functions and services supported by thesocial network system 122 include the identification of other users ofthe messaging system 100 with which a particular user has relationshipsor is “following,” and also the identification of other entities andinterests of a particular user.

The augmented reality system 124 provides functionality to generate andcause display of augmented reality elements in a GUI, including speechbubbles, as well as graphical elements representative of onomatopoeia.

The application server 112 is communicatively coupled to one or moredatabase server(s) 118, which facilitates access to a database(s) 120 inwhich is stored data associated with messages processed by the messagingserver application 114.

FIG. 2 is block diagram illustrating further details regarding themessaging system 100, according to example embodiments. Specifically,the messaging system 100 is shown to comprise the messaging clientapplication 104 and the application server 112, which in turn embody anumber of some subsystems, namely an ephemeral timer system 202, acollection management system 204 and an annotation system 206.

The ephemeral timer system 202 is responsible for enforcing thetemporary access to content permitted by the messaging clientapplication 104 and the messaging server application 114. To this end,the ephemeral timer system 202 incorporates a number of timers that,based on duration and display parameters associated with a message, orcollection of messages (e.g., a SNAPCHAT story), selectively display andenable access to messages and associated content via the messagingclient application 104. Further details regarding the operation of theephemeral timer system 202 are provided below.

The collection management system 204 is responsible for managingcollections of media (e.g., collections of text, image video and audiodata). In some examples, a collection of content (e.g., messages,including images, video, text and audio) may be organized into an “eventgallery” or an “event story.” Such a collection may be made availablefor a specified time period, such as the duration of an event to whichthe content relates. For example, content relating to a music concertmay be made available as a “story” for the duration of that musicconcert. The collection management system 204 may also be responsiblefor publishing an icon that provides notification of the existence of aparticular collection to the user interface of the messaging clientapplication 104.

The collection management system 204 furthermore includes a curationinterface 208 that allows a collection manager to manage and curate aparticular collection of content. For example, the curation interface208 enables an event organizer to curate a collection of contentrelating to a specific event (e.g., delete inappropriate content orredundant messages). Additionally, the collection management system 204employs machine vision (or image recognition technology) and contentrules to automatically curate a content collection. In certainembodiments, compensation may be paid to a user for inclusion of usergenerated content into a collection. In such cases, the curationinterface 208 operates to automatically make payments to such users forthe use of their content.

The annotation system 206 provides various functions that enable a userto annotate or otherwise modify or edit media content associated with amessage. For example, the annotation system 206 provides functionsrelated to the generation and publishing of media overlays for messagesprocessed by the messaging system 100. The annotation system 206operatively supplies a media overlay (e.g., a SNAPCHAT filter) to themessaging client application 104 based on a geolocation of the clientdevice 102. In another example, the annotation system 206 operativelysupplies a media overlay to the messaging client application 104 basedon other information, such as, social network information of the user ofthe client device 102. A media overlay may include audio and visualcontent and visual effects. Examples of audio and visual content includepictures, texts, logos, animations, and sound effects. An example of avisual effect includes color overlaying. The audio and visual content orthe visual effects can be applied to a media content item (e.g., aphoto) at the client device 102. For example, the media overlayincluding text that can be overlaid on top of a photograph generatedtaken by the client device 102. In another example, the media overlayincludes an identification of a location overlay (e.g., Venice beach), aname of a live event, or a name of a merchant overlay (e.g., BeachCoffee House). In another example, the annotation system 206 uses thegeolocation of the client device 102 to identify a media overlay thatincludes the name of a merchant at the geolocation of the client device102. The media overlay may include other indicia associated with themerchant. The media overlays may be stored in the database(s) 120 andaccessed through the database server(s) 118.

In one example embodiment, the annotation system 206 provides auser-based publication platform that enables users to select ageolocation on a map, and upload content associated with the selectedgeolocation. The user may also specify circumstances under which aparticular media overlay should be offered to other users. Theannotation system 206 generates a media overlay that includes theuploaded content and associates the uploaded content with the selectedgeolocation.

In another example embodiment, the annotation system 206 provides amerchant-based publication platform that enables merchants to select aparticular media overlay associated with a geolocation via a biddingprocess. For example, the annotation system 206 associates the mediaoverlay of a highest bidding merchant with a corresponding geolocationfor a predefined amount of time

FIG. 3 is a schematic diagram 300 illustrating data which may be storedin the database(s) 120 of the messaging server system 108, according tocertain example embodiments. While the content of the database(s) 120 isshown to comprise a number of tables, it will be appreciated that thedata could be stored in other types of data structures (e.g., as anobject-oriented database).

The database(s) 120 includes message data stored within a message table314. The entity table 302 stores entity data, including an entity graph304. Entities for which records are maintained within the entity table302 may include individuals, corporate entities, organizations, objects,places, events etc. Regardless of type, any entity regarding which themessaging server system 108 stores data may be a recognized entity. Eachentity is provided with a unique identifier, as well as an entity typeidentifier (not shown).

The entity graph 304 furthermore stores information regardingrelationships and associations between entities. Such relationships maybe social, professional (e.g., work at a common corporation ororganization) interested-based or activity-based, merely for example.

The database(s) 120 also stores annotation data, in the example form offilters, in an annotation table 312. Filters for which data is storedwithin the annotation table 312 are associated with and applied tovideos (for which data is stored in a video table 310) and/or images(for which data is stored in an image table 308). Filters, in oneexample, are overlays that are displayed as overlaid on an image orvideo during presentation to a recipient user. Filters may be of variestypes, including a user-selected filters from a gallery of filterspresented to a sending user by the messaging client application 104 whenthe sending user is composing a message. Other types of filers includegeolocation filters (also known as geo-filters) which may be presentedto a sending user based on geographic location. For example, geolocationfilters specific to a neighborhood or special location may be presentedwithin a user interface by the messaging client application 104, basedon geolocation information determined by a GPS unit of the client device102. Another type of filer is a data filer, which may be selectivelypresented to a sending user by the messaging client application 104,based on other inputs or information gathered by the client device 102during the message creation process. Example of data filters includecurrent temperature at a specific location, a current speed at which asending user is traveling, battery life for a client device 102 or thecurrent time.

Other annotation data that may be stored within the image table 308 isso-called “lens” data. A “lens” may be a real-time special effect andsound that may be added to an image or a video.

As mentioned above, the video table 310 stores video data which, in oneembodiment, is associated with messages for which records are maintainedwithin the message table 314. Similarly, the image table 308 storesimage data associated with messages for which message data is stored inthe entity table 302. The entity table 302 may associate variousannotations from the annotation table 312 with various images and videosstored in the image table 308 and the video table 310.

A story table 306 stores data regarding collections of messages andassociated image, video or audio data, which are compiled into acollection (e.g., a SNAPCHAT story or a gallery). The creation of aparticular collection may be initiated by a particular user (e.g., eachuser for which a record is maintained in the entity table 302) A usermay create a “personal story” in the form of a collection of contentthat has been created and sent/broadcast by that user. To this end, theuser interface of the messaging client application 104 may include anicon that is user selectable to enable a sending user to add specificcontent to his or her personal story.

A collection may also constitute a “live story,” which is a collectionof content from multiple users that is created manually, automaticallyor using a combination of manual and automatic techniques. For example,a “live story” may constitute a curated stream of user-submitted contentfrom varies locations and events. Users, whose client devices havelocation services enabled and are at a common location event at aparticular time may, for example, be presented with an option, via auser interface of the messaging client application 104, to contributecontent to a particular live story. The live story may be identified tothe user by the messaging client application 104, based on his or herlocation. The end result is a “live story” told from a communityperspective.

A further type of content collection is known as a “location story”,which enables a user whose client device 102 is located within aspecific geographic location (e.g., on a college or university campus)to contribute to a particular collection. In some embodiments, acontribution to a location story may require a second degree ofauthentication to verify that the end user belongs to a specificorganization or other entity (e.g., is a student on the universitycampus).

FIG. 4 is a schematic diagram illustrating a structure of a message 400,according to some in some embodiments, generated by a messaging clientapplication 104 for communication to a further messaging clientapplication 104 or the messaging server application 114. The content ofa particular message 400 is used to populate the message table 314stored within the database(s) 120, accessible by the messaging serverapplication 114. Similarly, the content of a message 400 is stored inmemory as “in-transit” or “in-flight” data of the client device 102 orthe application server 112. The message 400 is shown to include thefollowing components:

-   -   A message identifier 402: a unique identifier that identifies        the message 400.    -   A message text payload 404: text, to be generated by a user via        a user interface of the client device 102 and that is included        in the message 400.    -   A message image payload 406: image data, captured by a camera        component of a client device 102 or retrieved from memory of a        client device 102, and that is included in the message 400.    -   A message video payload 408: video data, captured by a camera        component or retrieved from a memory component of the client        device 102 and that is included in the message 400.    -   A message audio payload 410: audio data, captured by a        microphone or retrieved from the memory component of the client        device 102, and that is included in the message 400.    -   A message annotations 412: annotation data (e.g., filters,        stickers or other enhancements) that represents annotations to        be applied to message image payload 406, message video payload        408, or message audio payload 410 of the message 400.    -   A message duration parameter 414: parameter value indicating, in        seconds, the amount of time for which content of the message        (e.g., the message image payload 406, message video payload 408,        message audio payload 410) is to be presented or made accessible        to a user via the messaging client application 104.    -   A message geolocation parameter 416: geolocation data (e.g.,        latitudinal and longitudinal coordinates) associated with the        content payload of the message. Multiple message geolocation        parameter 416 values may be included in the payload, each of        these parameter values being associated with respect to content        items included in the content (e.g., a specific image into        within the message image payload 406, or a specific video in the        message video payload 408).    -   A message story identifier 418: identifier values identifying        one or more content collections (e.g., “stories”) with which a        particular content item in the message image payload 406 of the        message 400 is associated. For example, multiple images within        the message image payload 406 may each be associated with        multiple content collections using identifier values.    -   A message tag 420: each message 400 may be tagged with multiple        tags, each of which is indicative of the subject matter of        content included in the message payload. For example, where a        particular image included in the message image payload 406        depicts an animal (e.g., a lion), a tag value may be included        within the message tag 420 that is indicative of the relevant        animal. Tag values may be generated manually, based on user        input, or may be automatically generated using, for example,        image recognition.    -   A message sender identifier 422: an identifier (e.g., a        messaging system identifier, email address or device identifier)        indicative of a user of the client device 102 on which the        message 400 was generated and from which the message 400 was        sent    -   A message receiver identifier 424: an identifier (e.g., a        messaging system identifier, email address or device identifier)        indicative of a user of the client device 102 to which the        message 400 is addressed.

The contents (e.g. values) of the various components of message 400 maybe pointers to locations in tables within which content data values arestored. For example, an image value in the message image payload 406 maybe a pointer to (or address of) a location within an image table 308.Similarly, values within the message video payload 408 may point to datastored within a video table 310, values stored within the messageannotations 412 may point to data stored in an annotation table 312,values stored within the message story identifier 418 may point to datastored in a story table 306, and values stored within the message senderidentifier 422 and the message receiver identifier 424 may point to userrecords stored within an entity table 302.

FIG. 5 is a schematic diagram illustrating an access-limiting process500, in terms of which access to content (e.g., an ephemeral message502, and associated multimedia payload of data) or a content collection(e.g., an ephemeral message story 504) may be time-limited (e.g., madeephemeral).

An ephemeral message 502 is shown to be associated with a messageduration parameter 506, the value of which determines an amount of timethat the ephemeral message 502 will be displayed to a receiving user ofthe ephemeral message 502 by the messaging client application 104. Inone embodiment, where the messaging client application 104 is a SNAPCHATapplication client, an ephemeral message 502 is viewable by a receivinguser for up to a maximum of 10 seconds, depending on the amount of timethat the sending user specifies using the message duration parameter506.

The message duration parameter 506 and the message receiver identifier424 are shown to be inputs to a message timer 512, which is responsiblefor determining the amount of time that the ephemeral message 502 isshown to a particular receiving user identified by the message receiveridentifier 424. In particular, the ephemeral message 502 will only beshown to the relevant receiving user for a time period determined by thevalue of the message duration parameter 506. The message timer 512 isshown to provide output to a more generalized ephemeral timer system202, which is responsible for the overall timing of display of content(e.g., an ephemeral message 502) to a receiving user.

The ephemeral message 502 is shown in FIG. 5 to be included within anephemeral message story 504 (e.g., a personal SNAPCHAT story, or anevent story). The ephemeral message story 504 has an associated storyduration parameter 508, a value of which determines a time-duration forwhich the ephemeral message story 504 is presented and accessible tousers of the messaging system 100. The story duration parameter 508, forexample, may be the duration of a music concert, where the ephemeralmessage story 504 is a collection of content pertaining to that concert.Alternatively, a user (either the owning user or a curator user) mayspecify the value for the story duration parameter 508 when performingthe setup and creation of the ephemeral message story 504.

Additionally, each ephemeral message 502 within the ephemeral messagestory 504 has an associated story participation parameter 510, a valueof which determines the duration of time for which the ephemeral message502 will be accessible within the context of the ephemeral message story504. Accordingly, a particular ephemeral message story 504 may “expire”and become inaccessible within the context of the ephemeral messagestory 504, prior to the ephemeral message story 504 itself expiring interms of the story duration parameter 508. The story duration parameter508, story participation parameter 510, and message receiver identifier424 each provide input to a story timer 514, which operationallydetermines, firstly, whether a particular ephemeral message 502 of theephemeral message story 504 will be displayed to a particular receivinguser and, if so, for how long. Note that the ephemeral message story 504is also aware of the identity of the particular receiving user as aresult of the message receiver identifier 424.

Accordingly, the story timer 514 operationally controls the overalllifespan of an associated ephemeral message story 504, as well as anindividual ephemeral message 502 included in the ephemeral message story504. In one embodiment, each and every ephemeral message 502 within theephemeral message story 504 remains viewable and accessible for atime-period specified by the story duration parameter 508. In a furtherembodiment, a certain ephemeral message 502 may expire, within thecontext of ephemeral message story 504, based on a story participationparameter 510. Note that a message duration parameter 506 may stilldetermine the duration of time for which a particular ephemeral message502 is displayed to a receiving user, even within the context of theephemeral message story 504. Accordingly, the message duration parameter506 determines the duration of time that a particular ephemeral message502 is displayed to a receiving user, regardless of whether thereceiving user is viewing that ephemeral message 502 inside or outsidethe context of an ephemeral message story 504.

The ephemeral timer system 202 may furthermore operationally remove aparticular ephemeral message 502 from the ephemeral message story 504based on a determination that it has exceeded an associated storyparticipation parameter 510. For example, when a sending user hasestablished a story participation parameter 510 of 24 hours fromposting, the ephemeral timer system 202 will remove the relevantephemeral message 502 from the ephemeral message story 504 after thespecified 24 hours. The ephemeral timer system 202 also operates toremove an ephemeral message story 504 either when the storyparticipation parameter 510 for each and every ephemeral message 502within the ephemeral message story 504 has expired, or when theephemeral message story 504 itself has expired in terms of the storyduration parameter 508.

In certain use cases, a creator of a particular ephemeral message story504 may specify an indefinite story duration parameter 508. In thiscase, the expiration of the story participation parameter 510 for thelast remaining ephemeral message 502 within the ephemeral message story504 will determine when the ephemeral message story 504 itself expires.In this case, a new ephemeral message 502, added to the ephemeralmessage story 504, with a new story participation parameter 510,effectively extends the life of an ephemeral message story 504 to equalthe value of the story participation parameter 510. The ephemeralmessage story may include a speech bubble displayed within apresentation of a space.

Responsive to the ephemeral timer system 202 determining that anephemeral message story 504 has expired (e.g., is no longer accessible),the ephemeral timer system 202 communicates with the messaging system100 (and, for example, specifically the messaging client application 104to cause an indicium (e.g., an icon) associated with the relevantephemeral message story 504 to no longer be displayed within a userinterface of the messaging client application 104. Similarly, when theephemeral timer system 202 determines that the message durationparameter 506 for a particular ephemeral message 502 has expired, theephemeral timer system 202 causes the messaging client application 104to no longer display an indicium (e.g., an icon or textualidentification) associated with the ephemeral message 502. In someembodiments, the speech bubble may only be displayed for a period oftime defined by the ephemeral timer system 202. For example, uponexpiration of the time period, the speech bubble may vanish from apresentation of a space, and in further embodiments, may be replaced bya different speech bubble altogether.

FIG. 6 is a block diagram 600 illustrating one possible implementationof components of the augmented reality system 124. In variousembodiments, such components configure the augmented reality system 124to cause display of a presentation of a space, detect speech, identify asource of the speech, determine the location of a depiction of thesource of the speech in the presentation of the space, transcribe thespeech to a text string, generate a speech bubble based on the textstring, and cause display of the speech bubble at a position in thepresentation of the space. The augmented reality system 124 is shown asincluding a presentation module 602, a detection module 604, anidentification module 606, and a transcription module 608, all, or some,configured to communicate with each other (e.g., via a bus, sharedmemory, or a switch). Any one or more of these modules may beimplemented using one or more processors 610 (e.g., by configuring suchone or more processors to perform functions described for that module)and hence may include one or more of the processors 610.

Any one or more of the modules described may be implemented usinghardware alone (e.g., one or more of the processors 610 of a machine) ora combination of hardware and software. For example, any moduledescribed of the augmented reality system 124 may physically include anarrangement of one or more of the processors 610 (e.g., a subset of oramong the one or more processors of the machine) configured to performthe operations described herein for that module. As another example, anymodule of the engagement tracking system 610 may include software,hardware, or both, that configure an arrangement of one or moreprocessors 610 (e.g., among the one or more processors of the machine)to perform the operations described herein for that module. Accordingly,different modules of the engagement tracking system 610 may include andconfigure different arrangements of such processors 610 or a singlearrangement of such processors 610 at different points in time.Moreover, any two or more modules of the augmented reality system 124may be combined into a single module, and the functions described hereinfor a single module may be subdivided among multiple modules.Furthermore, according to various example embodiments, modules describedherein as being implemented within a single machine, database, or devicemay be distributed across multiple machines, databases, or devices.

FIG. 7 is a flowchart illustrating various operations of the augmentedreality system 124 in performing a method 700 for generating and causingdisplay of a speech bubble in a graphical user interface, according tocertain example embodiments. Operations of the method 700 may beperformed by the modules described above with respect to FIG. 6 . Asshown in FIG. 7 , the method 700 includes one or more operations 702,704, 706, 708, 710 and 712. In some example embodiments, the method 700may be performed by the augmented reality system 124 in real-time duringa video chat between client devices. For example, as users of the clientdevices speak to one another, the method 700 may be performed togenerate and cause display of speech bubbles within the correspondingdisplays of the client devices.

Operation 702 may be performed by the presentation module 602. Atoperation 702, the presentation module 602 generates and causes displayof a presentation of a space at a client device (e.g., client device102). For example, the client device 102 may have an integrated camera,and may capture and display an image of a space. The presentation of thespace may include a depiction of a first person.

Operation 704 may be performed by the detection module 604. At operation704, the detection module 604 detects sounds (e.g., via a microphonecomponent of a mobile computing device) that include speech. The speechmay include speech properties such as a volume, a cadence, a tone, aswell as a length of the speech. For example, the detection module 604may capture ambient sound, and detect speech in the ambient sound basedon various speech detection techniques as discussed above. The detectionmodule 604 may then extract the speech properties from the audio datathat contains the speech.

Operation 706 may be performed by the identification module 606. Atoperation 706, the identification module 606 identifies the first personas a source of the speech. For example, the identification module 606may detect movement of one or more facial landmarks of the first personbased on the image of the space. The identification module 606 maydetermine that the facial landmarks of the first person indicate thattheir mouth was moving (i.e., indicating that they were speaking). Basedon the facial landmarks of the first person indicating that a mouth ofthe first person was moving at the time that the speech was detected,the identification module 606 may determine that the first person wasthe source of the speech. In response to determining that the firstperson was the source of the speech, the identification module 606determines a location of the first person in the image in order toappropriately place the speech bubble.

In further embodiments, the identification module 606 may employ speechrecognition techniques to identify the first person as the source of thespeech. For example, the first person may have an associated userprofile that includes speech data, such that the first person may beidentified based on the speech data. Upon detecting the speech, theidentification module 606 may determine that based on the speech dataand the speech, that the source of the speech is the first person. Upondetermining that the source of the speech is the first person, theidentification module 606 may determine that the image includes adepiction of the first person based on the facial landmark recognitiondata and the image data.

In instances where the source of the speech is a radio, television,telephone and/or mobile device, the identification module 606 may applyacoustic source localization techniques. Acoustic source localizationinclude techniques for locating a source of a source given measurementsof a sound field. For acoustic localization this means that if thesource direction is measured at two or more locations in space, it ispossible to triangulate its location. For example, the identificationmodule 606 may record the speech as segments of audio data, wherein eachsegment of the audio data is recorded at a slightly different position,due to inherent movement of the recording device (e.g., a user holding amobile phone will inadvertently move the mobile phone even slightlyduring recording). The identification module 606 determines a locationof the speech based on triangulation of the segments of audio data. Theidentification module 606 therefore determines the source of the speechbased on the location.

The sound field can be described using physical quantities like soundpressure and particle velocity. By measuring these properties it is(indirectly) possible to obtain a source direction.

Operation 708 may be performed by the transcription module 608. Atoperation 708, the transcription module 608 transcribes the speech to atext string. The transcription module 608 may reside within a clientdevice 102, performing the transcription of the speech to text at theclient device 102 itself, while in other example embodiments, thetranscription module 608 may reside within a server system, remote fromthe client device 102, and delivering the transcribed speech to theclient device 102.

In response to the detection module 604 detecting the speech, thetranscription module 608 may record the speech to a database (e.g.,database 120). In some example embodiments, the transcription module 608may not record the speech to the database 120 at all, and may insteadtranscribe the speech to a text string in real time based on speechrecognition technology known to persons of skill in the art.

In some example embodiments, the transcription module 608 determinesappropriate punctuation to apply to the text string based on the speechproperties, including the cadence of the speech. For example, based onthe inflection of the speech, the transcription module 608 may select acomma, a question mark, period, exclamation point, ellipsis, or thelike.

In some example embodiments, the transcription module 608 may translatethe speech from a first language to a second language, based on a userlanguage preference, or based on a user input specifying a translationrequest. For example, a user of the client device 102 may have anassociated user profile that includes a language preference specifying alanguage (e.g., the second language). Upon detecting the speech, thedetection module 604 determines that the speech is in a first language.The transcription module 608 may transcribe the speech into a textstring, and translate the text string from the first language to thesecond language.

In further example embodiments, a user of the client device 102 mayprovide a user input specifying a translation request to translate thespeech from the first language to a language specified by the user. Forexample, a user of the client device 102 may provide a user inputrequesting that the speech be translated from a first language to asecond language specified by the user. In some embodiments, thetranscription module 608 may automatically detect the language of thespeech, while in other embodiments the user may specify the language ofthe speech as well as the language to translate the speech.

Operation 710 may be performed by the presentation module 602. Atoperation 710, the presentation module 602 generates a speech bubblethat includes a presentation of the text string, based on the speechproperties, a location of the source of the speech in the presentation,and the text string. The speech bubble may for example include a mainbody portion to include a presentation of the text string, and a tailportion to indicate a source of the speech. In instances where more thanone sources of a speech have been identified, the presentation module602 may generate a speech bubble that includes multiple tail portions,wherein each tail portion is directed at a source of the speech. Infurther embodiments, the shape of the speech bubble may be based on anemotional effect of the speech, wherein the emotional effect may bedetermined based on the speech properties.

The size of the speech bubble may be based on the length of the textstring. For example, the presentation module 602 may generate the speechbubble such that the text string is entirely enclosed and encompassed bythe speech bubble. In some example embodiments, the presentation module602 may present only a portion of the text string at a given time byonly displaying single sentences of the text string at a time, or bybreaking the text string into portions based on natural pauses andbreaks in the speech.

Operation 712 may be performed by the presentation module 602. Atoperations 712, the presentation module 602 causes display of the speechbubble at a position in the presentation of the space, based on thelocation of the source of the speech. In some example embodiments, thepresentation module 602 identifies the position to display the speechbubble based on the location of the source of the speech, as well aslocations of significant elements in the presentation. For example, thepresentation module 602 may identify a position in the presentation ofthe space that does not include any significant elements (e.g., faces).The presentation module 602 may thereby display the speech bubble at theposition without obstructing any significant elements in thepresentation.

FIG. 8 is a diagram illustrating various operations of the augmentedreality system 150 in performing a method 800 for generating the speechbubble based on an emotional effect, according to certain exampleembodiments. Operations of the method 800 may be performed by themodules described above with respect to FIG. 6 . As shown in FIG. 8 ,the method 800 includes one or more operations 802, 804, and 806 thatmay be performed as part (e.g., a precursor task, a subroutine, or aportion) of the method 700, according to some example embodiments.

Operation 802 may be performed by the detection module 604. At operation802, the detection module 802 determines an emotional effect of thespeech based on one or more of the speech properties, facialrecognition, and the speech itself. For example, to determine theemotional effect of the speech, the detection module 604 may applyfacial landmark recognition techniques to analyze facial landmarks of aperson identified as the source of the speech. In further embodiments,the detection module 604 determines the emotional effect of the speechbased on the speech properties including the volume and cadence of thespeech. For example, a high volume may indicate excitement or anger,while a low volume may indicate shyness.

In further embodiments, the detection module 604 may determine theemotional effect of the speech based on definitions of keywords in thecontext of the speech. For example, the detection module 604 may accessthe transcribed text string of the speech and determine definitions foreach word of the text string. The detection module 604 may therebycompare the definitions of the speech to an emotional effect library,wherein the emotional effect library includes a set of emotions andcorresponding words and definitions. The detection module 604 maythereby select an appropriate emotional effect based on the words and/ordefinitions.

Operation 804 may be performed by the presentation module 602. Atoperation 804, the presentation module 602 accesses a speech bubblelibrary that includes a set of speech bubble themes. The speech bubblethemes indicate a design and form to be applied to the speech bubblebased on the emotional effect. For example, an emotional effect of“angry” may have a corresponding speech bubble theme that causes thespeech bubble to display as a red jagged bubble, with red text andanimated fire, while an emotional effect of “sad” may have acorresponding speech bubble theme that causes the speech bubble todisplay as a drooping blue bubble with frowny faces and black text. Thespeech bubble themes may also have corresponding graphical elements andicon to be displayed with the speech bubbles in the presentation of thespace (e.g., hearts, smiley faces, frowny faces, etc.).

Operation 806 may be performed by the presentation module 602. Atoperation 806, the presentation module 602 selects a speech bubble themebased on the emotional effect.

FIG. 9 is a flowchart illustrating various operations of the augmentedreality system 150 in performing a method 900 for causing display of agraphical element based on an onomatopoeia, according to certain exampleembodiments. Operations of the method 900 may be performed by themodules described above with respect to FIG. 6 . As shown in FIG. 9 ,the method 900 includes one or more operations 902, 904, 906, and 908that may be performed as part (e.g., a precursor task, a subroutine, ora portion) of the method 700, according to some example embodiments.

Operation 902 may be performed by the detection module 604. At operation902, the detection module 604 detects a non-verbal sound. Non-verbalsounds may include noises described by onomatopoeic words, such as“boom,” “pop,” “snkit,” “meow,” “moo,” “woof woof,” and the like.

Operation 904 may be performed by the detection module 604. At operation604, the detection module 604 compares the non-verbal sound to anonomatopoeia library that includes a list of onomatopoeic words. Forexample, the detection module 604 may record a wave form representativeof the non-verbal sound and compare the wave form to a list ofonomatopoeic words with corresponding wave forms in the onomatopoeialibrary.

Operation 906 may be performed by the detection module 604. At operation906, the detection module 604 identifies an appropriate onomatopoeiafrom the onomatopoeia library based on the non-verbal sounds (e.g., thewave form representative of the non-verbal sound). In some exampleembodiments, the onomatopoeia library may include a list of graphicalelements representative of their corresponding onomatopoetic word (e.g.,an explosion for “boom”).

Operation 908 may be performed by the presentation module 602. Atoperation 908, the presentation module 602 causes display of thegraphical element and the onomatopoetic word at a position in thepresentation of the space. In some example embodiments, the detectionmodule 604 may identify a location of the non-verbal sound. Thepresentation module 602 may cause display of the onomatopoetic word at aposition based on the location of the non-verbal sound.

FIG. 10 is an example of an augmented reality interface 1000 configuredto display a presentation 1010 of a space and a speech bubble 1020generated by the augmented reality system 150, according to certainexample embodiments. As shown, FIG. 10 includes the presentation 1010,speech bubble 1020, a first individual 1030, a text string 1040, and asecond individual 1050.

As shown in FIG. 10 , the presentation 1010 may include a depiction ofthe first individual 1030 and the second individual 1050, who may beengaged in a conversation. As discussed above, with respect tooperations 704 and 706 of FIG. 7 , the augmented reality system 150detects and identifies a source of speech based on factors that mayinclude facial landmarks of a user (e.g., the first user 1030), and/orspeech and facial landmark recognition technology. As shown in FIG. 10 ,the augmented reality system 150 identified the first individual 1030 asthe source of a speech.

As discussed in operation 708 of FIG. 7 , the augmented reality system150 transcribes the detected speech to a text string 1040, based onproperties of the speech that include volume, cadence, tone, and alength of the speech. For example, the text string 1040 may be displayedin different fonts based on the speech properties for emphasis and/or toindicate an emotional effect of the speech. In some example embodiments,the first individual 1030 may have an associated user profile thatincludes display preferences that alter a presentation of the speechbubble 1020 and the text string 1040. The user profile may indicate thattext strings associated with the user must be displayed in a specificfont (e.g., Times New Roman, Wingdings, Algeria), specific color (e.g.,blue, gold), specific language (e.g., English, Armenian, Chinese), etc.For example, in response to identifying the first individual 1030 as asource of the detected speech, the augmented reality system 150 mayextract facial landmarks of the first individual 1030 to identify acorresponding user profile of the first individual 1030 based on speechand/or facial landmark recognition technology. The augmented realitysystem 150 may display the text string based on the user profileinformation and/or the speech properties.

The speech bubble 1020 is generated based on the speech properties andthe presentation 1010. As discussed in operation 710 of FIG. 7 , and themethod 800 of FIG. 8 , the augmented reality system 150 may generate andcause display of the speech bubble 1020 based on the speech propertiesof the detected speech, as well as the presentation 1010. For example,the presentation 1010 includes a depiction of the first individual 1030and the second individual 1050 at positions in the presentation 1010.The augmented reality system 150 may identify an appropriate location inthe presentation 1010 to display the speech bubble 1020 so that thespeech bubble 1020 does not block or otherwise cover elements in thepresentation 1010, including for example, the first individual 1030 andthe second individual 1050. A size of the speech bubble 1020 may bebased on available/unoccupied space in the presentation 1010, as well asbased on speech properties.

Consider an illustrative explanation of FIG. 10 , wherein a user of aclient device 102 displays the presentation 1010 of the space. As shownin FIG. 10 , the presentation 1010 includes a depiction of the firstindividual 1030 and the second individual 1050. As the first individual1030 speaks, the augmented reality system 150 detects the speech andidentifies the first individual 1030 as a source of the speech based onfactors discussed above, including an indication that the firstindividual 1030 is speaking based on facial landmarks of the firstindividual 1030 (e.g., facial landmarks indicate that lips are moving).Upon identifying the first individual 1030 as the source of the detectedspeech, the augmented reality system 150 transcribes the speech to thetext string 1040, and generates a speech bubble 1020 based on at leastspeech properties of the speech. In some example embodiments, the speechbubble 1020 may additionally be based on a length of the text string.The augmented reality system 150 displays the speech bubble 1020 at aposition in the presentation 1010 based on the source of the speech andthe available/unoccupied space, in real-time.

FIG. 11 is an example of an augmented reality interface 1100 configuredto display an augmented reality speech bubble 1110, according to certainexample embodiments. FIG. 11 includes a speech bubble 1110, anindividual 1120, a text string 1130, and graphical elements 1140.

As discussed above, with respect to FIG. 8 , the augmented realitysystem 150 may determine an emotional effect of the detected speech. Insome example embodiments, the augmented reality system 150 may determinethat the speech includes musical elements, indicating that the speech issinging, or a song. For example, the augmented reality system 150 maycompare the detected speech to a musical library to determine if thespeech matches an existing song. In response to a determination that thespeech includes musical elements, the augmented reality system 150 maycause display of a graphical element to indicate that the speech hasmusical elements (e.g., graphical elements 1140 includes musical notes).

In some example embodiments as discussed above, the augmented realitysystem 150 generates the speech bubble 1110 based on speech propertiesand the emotional effect.

FIG. 12 is an example of an augmented reality interface 1200 configuredto display augmented reality onomatopoeia 1210 as discussed in FIG. 9 ,according to certain example embodiments.

As discussed in FIG. 9 , the augmented reality system 150 may detect anon-verbal sound, and compare the non-verbal sound to an onomatopoeialibrary. Upon comparing the non-verbal sound to the onomatopoeialibrary, the augmented reality system 150 may select an appropriategraphical element representative of the onomatopoeia to display in theaugmented reality interface 1200.

In some example embodiments, the augmented reality system 150 may detecta source of the non-verbal sound based on image and video data, and/orbased on audio location techniques. Audio location include techniquesfor performing accurate three-dimensional location sensing using audiohardware of a mobile device (e.g., client deice 102). In suchembodiments, the time-of-flight of a sound is used to determine theaccurate location of a source of the sound.

As depicted in FIG. 12 , the augmented reality system 150 detects anon-verbal sound and identifies a location of a source of the non-verbalsound based on image and/or audio location techniques. For example, theaugmented reality system 150 may detect a change in the image data thatcorresponds in time to the detection of the non-verbal sound. Based onthe change in the image data occurring simultaneously, or nearsimultaneously, to the detection of the non-verbal sound, the augmentedreality system 150 may determine a location of the sound.

FIG. 13 is a diagram illustrating various augmented reality speechbubbles 1300, according to certain example embodiments. FIG. 13 includesspeech bubbles 1310, 1320, 1330, 1340, and 1350.

As discussed in operation 804 of FIG. 8 , the augmented reality system150 may select a speech bubble from a speech bubble library based on anemotional effect of the detected speech and the speech properties.

Software Architecture

FIG. 14 is a block diagram illustrating an example software architecture1406, which may be used in conjunction with various hardwarearchitectures herein described. FIG. 14 is a non-limiting example of asoftware architecture and it will be appreciated that many otherarchitectures may be implemented to facilitate the functionalitydescribed herein. The software architecture 1406 may execute on hardwaresuch as machine 1300 of FIG. 13 that includes, among other things,processors 1304, memory 1314, and I/O components 1318. A representativehardware layer 1452 is illustrated and can represent, for example, themachine 1400 of FIG. 14 . The representative hardware layer 1452includes a processing unit 1454 having associated executableinstructions 1404. Executable instructions 1404 represent the executableinstructions of the software architecture 1406, including implementationof the methods, components and so forth described herein. The hardwarelayer 1452 also includes memory and/or storage modules memory/storage1456, which also have executable instructions 1404. The hardware layer1452 may also comprise other hardware 1458.

In the example architecture of FIG. 14 , the software architecture 1406may be conceptualized as a stack of layers where each layer providesparticular functionality. For example, the software architecture 1406may include layers such as an operating system 1402, libraries 1420,applications 1416 and a presentation layer 1414. Operationally, theapplications 1416 and/or other components within the layers may invokeapplication programming interface (API) API calls 1408 through thesoftware stack and receive a response as in response to the API calls1408. The layers illustrated are representative in nature and not allsoftware architectures have all layers. For example, some mobile orspecial purpose operating systems may not provide aframeworks/middleware 1418, while others may provide such a layer.

The frameworks/middleware 1418 (also sometimes referred to asmiddleware) provide a higher-level common infrastructure that may beused by the applications 1416 and/or other software components/modules.For example, the frameworks/middleware 1418 may provide various graphicuser interface (GUI) functions, high-level resource management,high-level location services, and so forth. The frameworks/middleware1418 may provide a broad spectrum of other APIs that may be utilized bythe applications 1416 and/or other software components/modules, some ofwhich may be specific to a particular operating system 1402 or platform.

The applications 1416 include built-in applications 1438 and/orthird-party applications 1440. Examples of representative built-inapplications 1438 may include, but are not limited to, a contactsapplication, a browser application, a book reader application, alocation application, a media application, a messaging application,and/or a game application. Third-party applications 1440 may include anapplication developed using the ANDROID™ or IOS™ software developmentkit (SDK) by an entity other than the vendor of the particular platform,and may be mobile software running on a mobile operating system such asIOS™, ANDROID™, WINDOWS® Phone, or other mobile operating systems. Thethird-party applications 1440 may invoke the API calls 1408 provided bythe mobile operating system (such as operating system 1402) tofacilitate functionality described herein.

The applications 1416 may use built in operating system functions (e.g.,kernel 1422, services 1424 and/or drivers 1426), libraries 1420, andframeworks/middleware 1418 to create user interfaces to interact withusers of the system. Alternatively, or additionally, in some systemsinteractions with a user may occur through a presentation layer, such aspresentation layer 1414. In these systems, the application/component“logic” can be separated from the aspects of the application/componentthat interact with a user.

“EMPHEMERAL MESSAGE” in this context refers to a message that isaccessible for a time-limited duration. An ephemeral message may be atext, an image, a video and the like. The access time for the ephemeralmessage may be set by the message sender. Alternatively, the access timemay be a default setting or a setting specified by the recipient.Regardless of the setting technique, the message is transitory.

“MACHINE-READABLE MEDIUM” in this context refers to a component, deviceor other tangible media able to store instructions and data temporarilyor permanently and may include, but is not be limited to, random-accessmemory (RAM), read-only memory (ROM), buffer memory, flash memory,optical media, magnetic media, cache memory, other types of storage(e.g., Erasable Programmable Read-Only Memory (EEPROM)) and/or anysuitable combination thereof. The term “machine-readable medium” shouldbe taken to include a single medium or multiple media (e.g., acentralized or distributed database, or associated caches and servers)able to store instructions. The term “machine-readable medium” shallalso be taken to include any medium, or combination of multiple media,that is capable of storing instructions (e.g., code) for execution by amachine, such that the instructions, when executed by one or moreprocessors of the machine, cause the machine to perform any one or moreof the methodologies described herein. Accordingly, a “machine-readablemedium” refers to a single storage apparatus or device, as well as“cloud-based” storage systems or storage networks that include multiplestorage apparatus or devices. The term “machine-readable medium”excludes signals per se.

“COMPONENT” in this context refers to a device, physical entity or logichaving boundaries defined by function or subroutine calls, branchpoints, application program interfaces (APIs), or other technologiesthat provide for the partitioning or modularization of particularprocessing or control functions. Components may be combined via theirinterfaces with other components to carry out a machine process. Acomponent may be a packaged functional hardware unit designed for usewith other components and a part of a program that usually performs aparticular function of related functions. Components may constituteeither software components (e.g., code embodied on a machine-readablemedium) or hardware components. A “hardware component” is a tangibleunit capable of performing certain operations and may be configured orarranged in a certain physical manner. In various example embodiments,one or more computer systems (e.g., a standalone computer system, aclient computer system, or a server computer system) or one or morehardware components of a computer system (e.g., a processor or a groupof processors) may be configured by software (e.g., an application orapplication portion) as a hardware component that operates to performcertain operations as described herein. A hardware component may also beimplemented mechanically, electronically, or any suitable combinationthereof. For example, a hardware component may include dedicatedcircuitry or logic that is permanently configured to perform certainoperations. A hardware component may be a special-purpose processor,such as a Field-Programmable Gate Array (FPGA) or an ApplicationSpecific Integrated Circuit (ASIC). A hardware component may alsoinclude programmable logic or circuitry that is temporarily configuredby software to perform certain operations. For example, a hardwarecomponent may include software executed by a general-purpose processoror other programmable processor. Once configured by such software,hardware components become specific machines (or specific components ofa machine) uniquely tailored to perform the configured functions and areno longer general-purpose processors. It will be appreciated that thedecision to implement a hardware component mechanically, in dedicatedand permanently configured circuitry, or in temporarily configuredcircuitry (e.g., configured by software) may be driven by cost and timeconsiderations. Accordingly, the phrase “hardware component” (or“hardware-implemented component”) should be understood to encompass atangible entity, be that an entity that is physically constructed,permanently configured (e.g., hardwired), or temporarily configured(e.g., programmed) to operate in a certain manner or to perform certainoperations described herein. Considering embodiments in which hardwarecomponents are temporarily configured (e.g., programmed), each of thehardware components need not be configured or instantiated at any oneinstance in time. For example, where a hardware component comprises ageneral-purpose processor configured by software to become aspecial-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware components) at different times. Softwareaccordingly configures a particular processor or processors, forexample, to constitute a particular hardware component at one instanceof time and to constitute a different hardware component at a differentinstance of time. Hardware components can provide information to, andreceive information from, other hardware components. Accordingly, thedescribed hardware components may be regarded as being communicativelycoupled. Where multiple hardware components exist contemporaneously,communications may be achieved through signal transmission (e.g., overappropriate circuits and buses) between or among two or more of thehardware components. In embodiments in which multiple hardwarecomponents are configured or instantiated at different times,communications between such hardware components may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware components have access. Forexample, one hardware component may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware component may then, at alater time, access the memory device to retrieve and process the storedoutput. Hardware components may also initiate communications with inputor output devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein, “processor-implemented component”refers to a hardware component implemented using one or more processors.Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented components. Moreover, the one or more processorsmay also operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an Application ProgramInterface (API)). The performance of certain of the operations may bedistributed among the processors, not only residing within a singlemachine, but deployed across a number of machines. In some exampleembodiments, the processors or processor-implemented components may belocated in a single geographic location (e.g., within a homeenvironment, an office environment, or a server farm). In other exampleembodiments, the processors or processor-implemented components may bedistributed across a number of geographic locations.

“PROCESSOR” in this context refers to any circuit or virtual circuit (aphysical circuit emulated by logic executing on an actual processor)that manipulates data values according to control signals (e.g.,“commands”, “op codes”, “machine code”, etc.) and which producescorresponding output signals that are applied to operate a machine. Aprocessor may, for example, be a Central Processing Unit (CPU), aReduced Instruction Set Computing (RISC) processor, a ComplexInstruction Set Computing (CISC) processor, a Graphics Processing Unit(GPU), a Digital Signal Processor (DSP), an Application SpecificIntegrated Circuit (ASIC), a Radio-Frequency Integrated Circuit (RFIC)or any combination thereof. A processor may further be a multi-coreprocessor having two or more independent processors (sometimes referredto as “cores”) that may execute instructions contemporaneously.

“TIMESTAMP” in this context refers to a sequence of characters orencoded information identifying when a certain event occurred, forexample giving date and time of day, sometimes accurate to a smallfraction of a second.
